Blockchain - From the Basics to Advanced - A Free Course

Turn on CNBC or any business/ financial news channel today and you're likely to hear about Bitcoin. Blockchain is the technology behind Bitcoin and all cryptocurrencies. If you're not familiar with how blockchain works or you're looking for a simple explanation to share with your students, Common Craft has you covered. Blockchain Explained by Common Craft makes a great analogy between keeping a ledger of tangible assets to keeping a ledger of digital assets. The presentation of that analogy makes it easy to understand how blockchain works. 

Once you understand the basics of blockchain you might want to learn more about cryptocurrencies. Blockchain and Money is an open course from MIT. The course was originally taught in the fall of 2018, but all of the materials and lectures are still available for free. All twenty-three lectures in the course can be viewed in this YouTube playlist. It is a graduate course so I don't expect that high school students would be able to understand all of it, but an interested high school student could still glean some good lessons from it. 

H/T to Open Culture

Disclosure: I have a long-standing in-kind relationship with Common Craft.

Common Craft Explains Blockchain

Turn on any of the 24/7 cable news networks today and you're likely to hear about Bitcoin and or blockchain. Bitcoin is in the news because of its wild fluctuations in value over the last year. Blockchain is what makes cryptocurrencies like Bitcoin possible. If that seems clear as mud, you should watch Common Craft's new video titled Blockchain Explained by Common Craft. The video does a great job of using a concept that we're all familiar with, ownership of physical property, to explain the Blockchain concept.


After watching Common Craft's video about blockchain, watch this video from Financial Post to learn how the blockchain concept is applied to Bitcoin and other cryptocurrencies.



Applications for Education
Bitcoin and other cryptocurrencies can provide good examples of the relative values of currency. I'd include it in a lesson about where the value of a currency is created. The end of the Financial Post's video raises a couple of points about potential problems with cryptocurrencies. Ask students to discuss and propose potential solutions to or safeguards against those problems related to the relative value of currencies.
